Boyd Limited, dhettleston, Glasgow, Scotland, at British company Filed Sept. 16, 1958, fier. No, 766,150 Claims priori application Great Britain Sept. 13, E57 6 Claims. (Cl. 57-38) This invention relates to a driving arrangement for a spinning, twisting and like textile machine, of the type in which a driven laterally extending endless belt running horizontally with its driving face vertical serves to drive rotatable members such as spindles or fiyers eac of which is rotatable about a fixed vertical axis, a whorl associated with each spindle or fiyer is moveable against the belt to cause the drive to be transmitted to the associated spindle or fiyer, and a second whorl associated with each spindle or iiycr is so mounted adjacent to the face of the belt remote from the first whorl as to be moveable to disengage the belt from the associated spindle or flyer and to maintain the belt out of engagement with the associated spindle or fiyer.

According to present practice, the first whorl of each set is disposed adjacent to one face of the belt and the second whorl of each set is disposed adjacent to the face of the belt remote from the first whorl, each set of whorls being spaced from an adjacent set by the associated spindle or flyer. When one of the second whorls is moved to disengage the belt from the associated spindle or fiver, there is a tendency for the portion of the belt in engagement with an adjacent spindle or flyer to be moved in the direction away from the said adjacent spindle or flyer, thus causing a reduction in the driving power on said adjacent spindle or flyer, and necessitating the provision of excess driving power to compensate for such a reduction in power.

The primary object of the present invention is to provide for disengaging the belt from a selected spindle or tlyer in such wise that there is no reduction in the driving power on an adjacent spindle or fiyer.

In a machine according to the invention the sets of whorls are arranged in groups consisting of two sets disposed adjacent to one another and one set spaced from the first-mentioned sets by at least one spindle or liver.

A driving arrangement as applied to a spinning machine is illustrated in the accompanying drawings in which:

FlGS. IA and 1B are side elevational views of adjacent portions of the spinning machine showing an arrangement in accordance with the invention;

FIGS. 2A and 2B are plan views of the portions or" the spinning machine and arrangment illustrated in FIGS. 1A and 18, respectively, and

FIG. 3 is a section on the line 3-3 of FIG. 1.

Referring to the drawings, it denotes a driven endless belt, part only being illustrated for clarity, that part, as shown, extending laterally of the machine and running in a horizontal path with its driving face vertical to drive spaced spindles 2, mounted on the frame of the machine and located in a straight line transversely of the machine, as shown in FIGS. 2A2B, each of which is rotatable about a fixed vertical axis. 4 denotes a whorl associated with each spindle 2 and moveable against the belt 1 to cause the drive to be transmitted to the associated spindle 2. 5 denotes a second whorl associated with each spindle 2 and so mounted adjacent to the face of the belt 1 remote from the whorl 4 as to be moveable to disengage the belt 1 from the associated spindle 2 and to maintain the belt 1 out of engagement with said spindle 2.

The sets of whorls i, 5 are arranged in groups consisting of two sets, the two sets shown in FIGS. lA-lB being denoted generally at 6, 7 disposed adjacent to one another. The two sets of the next group, shown in FIGS. lB-ZB, are denoted generally at 6a, 7a, spaced from the sets 6, 7 by two adjacent spindles 2,. A part of a whorl 4 of a set 612 is shown at the extreme right at FIG. 213.

Each set of whorls 4, 5 is mounted in spaced relationship on a lever 9 pivotally mounted at one end lll in the machine frame for swinging movement about a vertical axis. One arm of a bell-crank lever ll. (FIG. 3), pivoted about a horizontal axis in the machine frame is so engageable with each lever 9 as to urge the whorl 4 in the direction to cause the belt 1 to engage the asso ciated spindle 2.

Each lever 9 is formed with a projection 12. engageable with a spring-loaded lever 13 pivoted at 14 in the machine frame for swinging movement about a vertical axis. The lever 13 carries a brake pad 15 and is normally spring-urged in the direction to engage the associated spindle 2.

Adjacent levers 9 are interconnected by a tension spring 16, apart from the lever 9 at each end of the frame which is connected by a tension spring 17 to a fixed part 13 of the frame.

In FIG. 2A the two whorls 4 of the group of sets 6 and 7 are shown in the position in which they hold the belt 1 in engagement with the associated spindles 2, the belt being bent slightly around the spindles by the whorls 4 as illustrated, while in FIG. 2B, the two whorls 4 of the group of sets 6a, 7a shown in that view are out of engagement with the belt 1 which is held disengaged from the associated spindles 2 by the associated whorls 5. The brake pads 15 in FIG. 2A are shown out of engagement with the spindles 2, while in FIG. 2B the brake pads 15 are shown engaging the respective spindles 2.

In practice, when a lever ill is moved out of engagement with the associated lever 9 carrying, for example, the whorls 4 and 5 of the set 6 adjacent to the set 7, the lever 9 swings about its pivot ill under the influence of the associated spring 17 in the direction to move the associated whorl 4 away from the belt and cause the associated whorl 5 to disengage the belt 1 from the associated spindle 2. The angle of contact which the whorl 4 of the adjacent set 7 makes with the belt '1 remains unaltered and there is no reduction in the driving power imparted by the belt 1 to the spindle 2 associated with said set 7.

When a lever 11 is moved out of engagement with the associated lever 9 carrying the whorls 4 and 5 of set 6a of the group in FIG. 2B, the lever 9 swings about the pivot under the influence of the associated spring 16 in the direction to cause the associated whorl 5 to disengage the belt 1 from the associated spindle 2. There may be a slight increase in the angle of contact which the whorl 4 of the set '7 of the group in FIG. 2A makes with the endless belt 1, but the distance between the two sets 7, 6a is such that the eiiect on the driving power imparted by the belt 1 to the associated spindle 2 is negligible.

With the arrangement described, the power required to drive each spindle 2 is just sutficient to drive the spindle 2 without being affected by stoppage of an adjacent spindle 2. The power consumed is therefore low and operation of the machine is more positive than in the arran ernent as heretofore constructed.

It is to be understood that the belt 1 may be associated with fiyers in lieu of spindles.

I claim:

In a driving arrangement for spinning, twisting and the like textile machines of the type including a frame, a plurality of rotatable members such as spindles or flyers mounted on the frame, an endless driven belt for driving the rotatable members having a driving face and including a driving run extending laterally of the machine frame in a horizontal generally straight path with its driving face vertical, said plurality of rotatable members being located in spaced relation along the laterally-extending driving run of the belt, each engageable by the driving face of the belt for rotation about a vertical axis, a first whorl associated with each rotatable member and movable against said belt to cause the drive from said belt to be transmitted to said rotatable member, and a second whorl associated with each rotatable member and so mounted adjacent to the face of said belt remote from said first whorl as to be movable to disengage said belt from the associated rotatable member and to maintain said belt out of engagement with said associated rotatable member, said first and second whorls associated with each of the plurality of rotatable members constituting a set, the improvement in the arrangement of the plurality of rotatable members and their associated sets of first and second whorls along the driving run of the belt in which the sets of whorls are arranged in groups each consisting of two sets of whorls disposed adjacent to one another along the laterally-extending driving run of the belt, and each group of whorls being spaced from an adjacent group of whorls along the laterally-extending driving run of the belt by two rotatable members, the arrangement of each group of whorls and the two rotatable members associated therewith along the laterally-extending driving run of the belt being such that when the belt 1 is disengaged from a selected one of the two rotatable members by its associated second whorl the first whorl associated with the other of the two rotatable members prevents any deflection of the belt therefrom and consequent reduction in the driving power imparted thereto by the belt.

2. A driving arrangement as claimed in claim 1, in which each set of whorls is mounted in spaced relation on a lever pivotally mounted in the machine frame for swinging movement about a vertical axis, and spring means normally urging the lever of each set in the direction to disengage the belt from the associated rotatable member.

3. A driving arrangement as claimed in claim 2, including a lever engageable with each lever carrying a set of whorls and operable to cause the appropriate whorl of the set to urge the endless belt into driving engagement with the associated rotatable member.

4. A driving arrangement as claimed in claim 2, including a brake associated with each rotatable member and 50 operatively engageable by the lever carrying the associated set of whorls.

5. In a driving arrangement for spinning, twisting and the like textile machines of the type including a frame, an endless driven belt having a driving face and including a driving run extending laterally of the machine with its driving face vertical, and a series of rotatable members mounted on the frame and located at spaced positions along and to be driven by the belt, each rotatable mcm er being engageable by the belt for rotation about a vertical axis, a first whorl associated with each rotatable member and located on the side of the belt opposite to that of sad member, said whorl being movable against said belt to cause the drive from said belt to be transmitted to said rotatable member, and a second whorl associated with each rotatable member and mounted on the opposite side of said belt from that of said first whorl for disengaging said belt lrom the associated rotatable member and to maintain said belt out of engagement with said associated rotatable member, the improvement in which said series of rotatable members is arranged in a substantially straight line laterally of the machine frame and the driving run or" the belt extends in a horizontal path along one side only of the series of rotatable members with its driving face adjacent thereto, and in which said series of rotatable members are arranged in pairs with respect to their associated whorls with the first and second whorls of each rotatable member of a pair of rotatable members locate along the belt between the positions of the rotatable members of the pair, the first and second whorls for the pair of rotatable members being movable to engage the belt between the positions of its engagement with the rotatable members of the pair, whereby the disengagement of the belt from one of the rotatable members of the pair does not afiect the engagement of the belt with the other rotatable member of the pair.

6. A driving arrangement for textile machines as claimed in claim 1, in which the whorls of each group are movable to engage the belt between the positions of its engagement with the two rotatable members associated with said group of whorls.
